Subject: Bluetooth: Add flag to track the real advertising state
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66c417c1ee01398ac5ab1c749a20c4d8ba50e9a9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: Add flag to track the real advertising state

Having a single HCI_ADVERTISING flag is problematic since it tries to
track both the real advertising state and the corresponding mgmt
setting. To make the logic simpler and more reliable add a new flag that
only tracks the actual advertising state that has been written to the
controller.
